The first collision energy-absorbing area and the second collision energy-absorbing area are both provided with collision energy-absorbing devices, and the collision energy-absorbing devices are collapsed and deformed under the collision working condition to absorb the energy of external collision, so that the collision energy transmitted to the passenger protection area is weakened, and the damage of the collision to passengers is reduced. Crash energy absorbers generally include an inner panel and an outer panel welded together with the outer panel positioned outside of the inner panel, the inner and outer panels collapsing and deforming during a crash condition to absorb crash energy.
However, the related impact energy absorbing device is limited only by the energy absorbed by the crush deformation of the inner and outer panels, and when the external impact energy is excessive, even if the inner and outer panels are crushed to the bottom, the impact energy transmitted to the occupant protection area cannot be weakened, resulting in increased injury to the occupant from the impact.
An exemplary, related art body-in-white includes a front rail assembly and a Shotgun assembly mounted on an outer side of the front rail assembly, the Shotgun assembly including a Shotgun inner panel and a Shotgun outer panel welded together, the Shotgun assembly collapsing to absorb energy of an external impact upon the external impact. However, the Shotgun assembly has limited energy absorption, and when the external impact energy is too high, even if the Shotgun assembly is completely crushed to the bottom, the collision energy transmitted to the occupant protection area cannot be reduced to the safe energy range, and the large collision energy still causes injury to the occupant.

Example one
Referring to fig. 1, an embodiment of the present application provides a collision energy absorbing device 10, which includes an inner plate 11, an outer plate 12 and an energy absorbing member 13, where the inner plate 11 and the outer plate 12 may be connected together by welding, clamping, or bolting, the inner plate 11 and the outer plate 12 are enclosed to form an accommodating cavity, and the energy absorbing member 13 is disposed in the accommodating cavity.
The energy absorber 13 has a first side surface abutting the inner panel 11 and a second side surface abutting the outer panel 12, so that the impact energy from the inner panel 11 or the outer panel 12 can be transmitted to the energy absorber 13. The energy absorbing piece 13 is provided with a plurality of independent and dispersed air holes, so that collision energy is consumed in the process of being transmitted along the hole walls of the air holes, and the energy absorbing effect is achieved.
Specifically, the hole walls of the air holes are connected, collision energy is transmitted along the hole walls, the transmission direction of the collision energy and the length of a transmission path are greatly increased by the hole walls, the collision energy is greatly weakened in the transmission process, and therefore the collision energy which can be absorbed by the collision energy absorption device 10 is increased.
When the external impact energy is large, the impact energy absorbing device 10 in this embodiment can not only absorb the impact energy through the collapsing deformation of the inner plate 11 and the outer plate 12, but also absorb a large amount of impact energy through the energy absorbing member 13, so that the impact energy absorbed by the impact energy absorbing device 10 is greatly increased.
The energy absorbing member 13 may include a foam metal, the foam metal may be foam nickel, foam aluminum alloy, or the like, and the foam metal has a certain rigidity, so that collision energy may be normally transmitted along the hole wall, and failure of the energy absorbing member 13 due to the fact that the hardness of the energy absorbing member 13 is too low and the collision energy cannot be normally transmitted in a collision process is avoided.
Preferably, the energy absorbing member 13 comprises a foamed aluminum alloy, the foamed aluminum alloy has independent and dispersed bubble structure or hollow particles in an aluminum base material, and has the characteristics of low density, high rigidity, good impact energy absorption, low thermal conductivity, low magnetic conductivity, high damping and the like, so that not only can the energy absorption effect of the collision energy absorbing device 10 be improved, but also the heat insulation performance of the collision energy absorbing device 10 can be improved, and the quality of the collision energy absorbing device 10 can be reduced.
Specifically, the density range of the foamed aluminum alloy is 0.2-1.1 g/cm < 3 >, the density range is only 1/10-1/3 of that of aluminum with the same volume, and compared with the aluminum block with the same volume arranged in the accommodating cavity, the foamed aluminum alloy can greatly reduce the mass of the collision energy absorption device 10.
Furthermore, the pore diameter of the air holes in the foamed aluminum alloy can be between 0.1mm and 10.0mm, so that the foamed aluminum alloy can absorb enough collision energy, and meanwhile, the consumption of the foamed aluminum alloy is reduced.
The total volume of the air holes in the foam aluminum alloy accounts for 40% -90% of the total volume of the foam aluminum alloy so as to improve the absorption rate of the foam aluminum alloy to impact energy, and particularly, when the total volume of the air holes in the foam aluminum alloy accounts for 84% of the total volume of the foam aluminum alloy and the foam aluminum alloy deforms by 50%, the foam aluminum alloy can absorb 2.5MJ/m3C energy. The low-density foam aluminum alloy material has strong capability of absorbing impact energy, the energy absorption efficiency basically can reach more than 50%, and the energy absorption efficiency of a platform area is 80-90%, so that external collision energy can be well absorbed, and impact damage is reduced.

Referring to FIG. 2, the impact energy absorber 10 of the present embodiment can be disposed outboard of the front rail assembly 22 as a Shotgun assembly, wherein the inner panel 11 corresponds to a Shotgun inner panel and the outer panel 12 corresponds to a Shotgun outer panel.
In the event of an external impact, the Shotgun assembly relies on the Shotgun inner panel and the Shotgun outer panel to deform by collapsing to absorb the energy of the external impact, and further relies on the energy absorber 13 to further absorb the energy so that the energy of the impact transmitted to the occupant protection zone is greatly reduced, thereby reducing the impact on the occupant.
In addition, the Shotgun assembly in this embodiment is located at the front end of the a-pillar 21 of the body-in-white 20, and the energy absorbing member 13 absorbs part of the collision energy, so that the collision energy borne by the Shotgun inner panel and the Shotgun outer panel is reduced, thereby preventing the Shotgun inner panel and the Shotgun outer panel from being crushed completely to the bottom to cause deformation of the a-pillar 21, and further preventing the situation that the vehicle door cannot be normally opened due to deformation of the a-pillar 21, so that after a collision occurs, the vehicle door can still be normally opened, and a passenger in the vehicle can open the vehicle door to escape, thereby improving the passive safety of the vehicle.
The energy absorbing piece 13 may be filled in a partial region of the accommodating cavity, for example, the energy absorbing piece 13 may be filled in a region which is relatively easy to bear collision energy in the accommodating cavity, and the energy absorbing piece 13 is not filled in a region which is not easy to bear collision energy in the accommodating cavity, so that the energy absorbing effect of the collision energy absorbing device 10 can be ensured, and the material consumption of the energy absorbing piece 13 can be reduced.
Preferably, the energy absorbing pieces 13 are filled at all positions in the accommodating cavity, so that the accommodating cavity is filled with the energy absorbing pieces 13, and the collision energy from all positions of the inner plate 11 or the outer plate 12 can be transmitted to the energy absorbing pieces 13, so that the energy absorbing efficiency of the energy absorbing pieces 13 is improved, and further the energy absorbing efficiency of the collision energy absorbing device 10 is improved.
